CHURN-DASHER.

SPECIFICATION forming part of Letters Patent No. 363,231, dated May 1'7,1887.

Application filed March 19, 1887. Serial No. 231,476. (NomodeL) To allwhom it may concern:

Be it known that I, SI-IELTON CITIZEN HAR R1soN,a citizen of the UnitedStates,and a resident of Rocky Mount, in the county of Frank lin andState of Virginia, have invented certain new and useful Improvements inOhurn- Dashers; and I do hereby declare that the following is a full,clear, and exact description of the invention, which will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, which form a part ofthis specification, and in which Figure l is a vertical sectional viewof a churn, showing my improved dasher in side view, and Fig.2 is avertical sectional view of the same.

Similar numerals of reference indicate corresponding parts in both thefigures.

My invention has relation to that class of churn-dashers in whicheross-pieces are piv otally attached to vertically reciprocatingdasher-staffs, so that the said cross-pieces may be rocked when thestaffs are reciprocated, thus churning the milk or cream in the churnand it consists in the improved construction and combination of parts ofsuch a dasher, as hereinafter more fully described and claimed.

In the accompanying drawings, the numeral 1 indicates thechurn-body,which is provided with the removable lid or cover 2, having arectangular central perforation, 3, which registers with two smallerrectangular pcrforations, 4, in the center of a cross-piece, 5, or toppiece of an upright frame, 6, secured upon theupper side of the cover.

The dasher-staffs 7 slide and fit with their upper portions in theperforation in the con ter of the lid or cover, and the upper ends, 8,of the dasher-staffs are reduced upon their meeting faces and slide inthe perforations in the top piece of the upright frame, a space beingformed between the said reduced ends.

A bolt, 9, passes through the upper portions of the side pieces of theupright frame and into the space between the reduced upper ends of thestaffs, and the central apertured portion, 10, of the operating-lever 11is pivoted upon this bolt, the side pieces, 12, of the frame formed atthe apertured middle of the lever, having the bolt passing through them.The

lever has two plates, 13, secured upon the un der side of its arms ashort distance from the dasher-staffs, and the lower faces of theseplates are formed with perforated cars 14, be-

tween which the upper perforated ends of two arms, 15, are pivoted uponbolts 16. Thelower ends, 17, of these arms are bent inward and formedwith lips l8,which straddle the dasherstaffs and are pivoted by means ofpins or bolts 19, passing through the lips and staffs; and it will beseen that as the lever is rocked the (flasher-staffs are alternatelyraised and depressed bythe arms being drawn upward and depressed by thearms of the lever.

The lower portions of the dasher-staffs have registering pairs oftransverse pins 20, and disks or cross-plates 21 have rectangularapertures at their mi'ddles, with which they are slipped upon thestaffs, and are retained upon the staffs by means of the pins, one pairof pins confining each disk or plate from above and one pair from below,the disk or plate, however, having free play between them. It will nowbe seen that as the dasher-staffs are reciprocated the ends of the disksor plates are alternately depressed and raised,the rocking disks orplates thus churning the milk or cream when the dasher is placed withina churn and the lever is rocked.

By rocking the lever comparatively slightly, and thus reciprocating thedasher-staffs merely a short space, the cross-pieces may be rockedconsiderably,as the transverse pins engage the apertured centers of thesaid disks or crossplates near the centers of them.

Having thus described my invention, Iclaim and desire to secure byLetters Patent of the United States 1. In a churn-dasher, thecombination of two reciprocating dasher-staffs having means forreciprocating them, and having pairs of registering transverse pinsinserted through them, with disks or cross-plates having apertures intheir centers and fitting with the said apertures upon the staffsbetween the pairs of transverse pins, as and for the purpose shown andset forth.

2. In a churn-dasher, the combination of a cover for the churn, having arectangular aperture and having an upright frame formed with twoapertures in its top piece registering with the rectangular aperture,two dasherstaffs sliding in the aperture in the lid or cover and havingtheir upper portions reduced upon the inner meeting faces, a leverhaving its middle formed into a frame and having a bolt passing throughthe side pieces of the upright frame and of the frame of the lever andin the space between the reduced ends of the staffs, arms pivotedbetween perforated lips upon the under sides of the arms of the leverand having their inwardly-bent ends formed with apertures and fittingloosely with thesaid apertu res upon the staffs, having registeringpairs 1 5 my own invention I have hereunto affixedmy 2o signature inpresence of two witnesses.
